ssh-audit
ssh-audit is a tool for ssh server auditing.
Features
- SSH1 and SSH2 protocol server support;
- grab banner, recognize device or software and operating system, detect compression;
- gather key-exchange, host-key, encryption and message authentication code algorithms;
- output algorithm information (available since, removed/disabled, unsafe/weak/legacy, etc);
- output algorithm recommendations (append or remove based on recognized software version);
- output security information (related issues, assigned CVE list, etc);
- analyze SSH version compatibility based on algorithm information;
- historical information from OpenSSH, Dropbear SSH and libssh;
- no dependencies, compatible with Python 2.6+, Python 3.x and PyPy;
Usage
usage: ssh-audit.py [-1246pbnvl] <host>
-1, --ssh1 force ssh version 1 only
-2, --ssh2 force ssh version 2 only
-4, --ipv4 enable IPv4 (order of precedence)
-6, --ipv6 enable IPv6 (order of precedence)
-p, --port=<port> port to connect
-b, --batch batch output
-n, --no-colors disable colors
-v, --verbose verbose output
-l, --level=<level> minimum output level (info|warn|fail)
- if both IPv4 and IPv6 are used, order of precedence can be set by using either
-46
or-64
. - batch flag
-b
will output sections without header and without empty lines (implies verbose flag). - verbose flag
-v
will prefix each line with section type and algorithm name.

ChangeLog
v1.7.0 (2016-10-26)
- implement options to allow specify IPv4/IPv6 usage and order of precedence
- implement option to specify remote port (old behavior kept for compatibility)
- add colors support for Microsoft Windows via optional colorama dependency
- fix encoding and decoding issues, add tests, do not crash on encoding errors
- use mypy-lang for static type checking and verify all code
v1.6.0 (2016-10-14)
- implement algorithm recommendations section (based on recognized software)
- implement full libssh support (version history, algorithms, security, etc)
- fix SSH-1.99 banner recognition and version comparison functionality
- do not output empty algorithms (happens for misconfigured servers)
- make consistent output for Python 3.x versions
- add a lot more tests (conf, banner, software, SSH1/SSH2, output, etc)
- use Travis CI to test for multiple Python versions (2.6-3.5, pypy, pypy3)
v1.5.0 (2016-09-20)
- create security section for related security information
- match and output assigned CVE list and security issues for Dropbear SSH
- implement full SSH1 support with fingerprint information
- automatically fallback to SSH1 on protocol mismatch
- add new options to force SSH1 or SSH2 (both allowed by default)
- parse banner information and convert it to specific software and OS version
- do not use padding in batch mode
